论文摘要
如果存在镜面物质但不能构成宇宙中的所有暗物质（DM），我们可以期望附加的DM组件只能在重力上与其他部门相互作用。重力相互作用组件的自然候选者之一是原始黑洞（PBH）。因此，如果存在镜像，但不能构成宇宙中的所有DM，则可以期望PBH的存在是其他DM组件的候选者。在这种情况下，其余的DM组件可以是PBHS或$ SU（3）\ Times SU（2）\ Times U（1）$ singlet粒子来自PBH。我们用镜子DM在PBH上显示限制。特别是，估计初始PBH质量为$ 10^{17} \ {\ rm g} \ sillssim m _ {\ rm pbh} \ sillesim 10^{23} \ {\ rm g} $，如果DM构成了Mirror Baryons和Pbhs。
If mirror matter exists but cannot comprise all of the dark matter (DM) in the universe, we can expect that the additional DM component may only interact with the other sectors gravitationally. One of the natural candidate of a gravitationally interacting component is a primordial black hole (PBH). Therefore, if mirror matter exists but cannot comprise all of the DM in the universe, the existence of PBH may be expected as a candidate of the additional DM component. In this case, the remaining DM components may be PBHs or $SU(3)\times SU(2)\times U(1)$ singlet particles from PBH. We show constraints on PBH with the mirror DM. Particularly, the initial PBH mass is estimated to be $10^{17} \ {\rm g} \lesssim M_{\rm PBH} \lesssim 10^{23} \ {\rm g}$, if the DM comprises mirror baryons and PBHs.
